Tips: In winter If you touch temperature sensor with your hand, you can run ac system in cooling mode. In summer, if you touch with a cold material to temperature sensor, you can run ac system in heating mode. I achieved best gas storage in heating mode.

Air Conditioner Disassembly

Take photos of electric cables to record connection.

Record Phase , Notr, and Ground cables of fuse to reinstall it in new place.

Remove all electric cables of inner and outer ac system.

In copper pipes, there is small amount of gas. Unscrew, copper pipes slowly. Wait 15 seconds, to allow gas discharge. If it takes more time, you couldn't achieve gas storage perfectly.

Unscrew pipes, and remove pipes.

Remove water pipe.

Remove legs of air conditioner from wall.

How to Fix Air Conditioner to New Place

For fitting of inner and outer ac systems to wall, select place that allows air flow.

Join copper pipes, electric cable, and water pipe. Then wrap with tape. By this way, you can easly bend your copper pipes without damage.

Clear faces of valves and copper pipes by hand. Also, you can use vacuum cleaner. Connect faces of copper pipes to valves. Keeping this position, tighten the nuts of copper pipes. If you don't keep pipes stable, it causes leakage of gas.

Connect electric cables.

Open valves of thin and large copper pipes slowly. You can hear gas flow inside pipes.

If fan or compressor of outer ac system (condenser) doesn't start, check capacitor.

If you can't activate heating mode, you probably have problem with four-way valve. If you decide to change your four way valve, becareful for plastic parts during soldering process.

To test performance of your air conditioner each year, run system 10 minutes for stabilization, measure input and output air temperature and measure current of ac system. If your parameters lower than normal mode, you can increase performance of ac system by cleaning it and charging gas.
